insects. So Conchologists find Calcar^ 

 eous soils also are richest in species. 

 For water shells, ponds and slow 

 streams are best. For land shells, 

 damp woods or other places where their 

 love of moisture can be gratified. 



During winter most of the species, if 

 not all, retire for hybernation. Then 

 they may be found sometimes in great 

 numbers under stones, bark, decaying 

 vegetation, &c, &c. 



TO CORRESPONDENTS. 



All communications to be sent to J. E. Eobson, Bellerby 

 Terrace, West Hartlepool ; or to S. L. Mosley Beau- 

 mont Park, Huddersfield. 



We have to thank Mr. F. Kerry, of 

 Harwich, for specimens of Reed Wren and 

 young, and also for the common Swift, sent 

 for figuring in our Bird Book. 



NOTES, CAPTURES, &c. 



The Hooded Crow at Hartlepool, 

 in July. — On Thursday, the 27 July, when 

 returning from Black Hall Rocks, I dis- 

 turbed a specimen of the Hooded Crow, that 

 had been feeding on the Sand-hills. I 

 watched it for half-a-mile or so, and it flew 

 to a wooded ravine called Hezleden or 

 Crimdon Dene. Probably it had a mate 

 there. Though no Ornithologist, I have 

 noticed these birds on their winter visit for 

 very many years. Last winter they were 

 unusually abundant, and owing to the long 

 continuance of severe weather, they stayed 

 very late with us ; but I never before saw 

 a specimen remain over the breeding season. 

 John E. Robson, West Hartlepool. 



Hermaphrodite A. Paphia. It may in- 

 terest the readers of the Young Naturalist to 



know that I captured on July 17th, a her- 

 maphrodite specimen of A. paphia. The 

 right wings are like the male, and the left 

 wing like the female, both in colour and 

 markings. — H. Robinson, Coventry. 



Abundance of Larvae of D. vinula, &c. 

 We were out last night and took about 50 

 larvae of this species, and a quantity of 

 S.populi. We also got 12 larvae that I take 

 to be N. dieted. Is not that a great quantity 

 to be taken at once? — A. Bramwell, 

 Gateshead. — (The larva of N. dictea is green- 

 ish white on the back, shading into green, 

 with a yellow stripe above the spiracles. It 

 is very bright and glossy, and cannot be 

 mistaken for any other Poplar feeder.

"The Spring migration of birds at 

 St. Leonards." — This is the title of a most 

 interesting paper sent us by its author, Mr. 

 J. H. Gurney Jun., F.L.S. It contains a host 

 of valuable little facts, gathered and placed 

 in a most readable form. By such observa- 

 tions alone can the natural history of a 

 species be fully made out.
